The Discovery of Nucleus
Write an essay in which you will discuss the discovery of the nucleus by E. Rutherford.
Your essay should involve some research and should answer the questions below in an organized, easy to read and convincing manner:
What experimental findings not be explained by J.J. Thompson’s model?
How did Rutherford conduct his experiment?
What lab materials did he use?
What did he see?
How did he interpret the results?
Why couldn’t the “plum-pudding” model explain Rutherford’s experimental results?
What did he propose instead? How does Rutherford’s hypothesis agree with his experimental results?
Why did he propose a planetary model of the atom? What could the atom’s planetary model account for? Later, the planetary model proved to be deficient as well (this is another topic, though).
